Title: Method of and apparatus for casting glass
IPC: C03B19/02
Filed: 1955-02-02
Abstract: 766,854. Glass manufacture. CORNING GLASS WORKS. Feb. 2, 1955 [Feb. 3, 1954], No. 3121/55. Class 56 A glass blank, e.g. an optical lens blank of from 4 to 18 inches in diameter and 2¢ to 14 inches thick, is cast in a mould which is lined with a thin flexible and readily yieldable metal foil which serves as a parting material and remains intact at the casting temperature, the glass being further heated within the mould to such an extent that the exposed glass is molten when the formation of the blank is completed. The blank is annealed within the mould and is then removed. If the glasscasting temperatiure is near the melting point of the foil, more than one layer of foil may be used to ensure separation of the blank from the mould. Aluminium and stainless steel foils are mentioned as suitable. In Fig. 1, the circular mould 10 is filled by a stream 12 from an orifice 16. The parting material 14 is shaped, to correspond with the mould, either before insertion in to the mould or in the mould by a roller or other tool. Heater coils 20, arranged as wheel spokes or in a spiral,. keep the surface of the glass at a temperature which avoids skin formation, the flow of the glass laterally in the mould being thus facilitated. The heat reflected by the foil above the glass level aids this flow. The mould may be of ceramic refractory or of metal, and may be supported on a table or carriage for subsequent removal to an annealing furnace. After cooling and removal of the blank and foil from the mould, the foil is removed by grinding or chemical treatment. A mould lined with foil may be used for remoulding glass, e.g., optical glass, in which case the mould is filled with chunks of flaw-free glass selected from a broken pot of optical glass. Specifications 639,772 and 739,964 are referred to.

Title: Improvements in high-speed automatic electric circuit-breakers
IPC: H01H71/68
Filed: 1927-02-04
Abstract: 287,283. Juhlin, G. A., Todd, R. W., and Metrapolitan-Vickers Electrical Co., Ltd. Feb. 4, 1927. Automatic circuit-breakers with compound movement have both cooperating contacts movable away from one another by high-speed opening mechanism, and both contacts are provided with loose handle mechanism operable so as to close the contacts simultaneously independent of the position of the closing part of the loose handle mechanism. Each contact 1 is mounted on a lever 2 which is pivoted at 3 to a spring-controlled link 4 and at 6 to an arm 7 which is pivoted at 10 to the frame and carries the armature 8 of the retaining magnet 9. Limited rotation of the lever 2 with respect to the arm 7 is permitted by a slot 11 in the lever engaging the pivot 10. For setting the breaker there are provided a handle 16 and closing solenoid 17, which act through a lever 18 and links 21 to rotate cranks 22, each of which is fast on a shaft 15 or integral with an arm 13 thereon. The arms 13 act on the links 4 to urge the contacts towards one another, by first moving the levers 2 about pivots 6 until the lostmotion of the slot 11 is taken up, and then moving lever 2 and arm 7 as one about the pivot 10 into the position shown in Fig. 2 where the magnets 9 retain the parts. Removal of the operating force allows the springs 5 to rotate the levers 2 about the pivots 6 so that the contacts are finally engaged (Fig. 3). The loose handle feature is obtained by means of another arm 14 loose on the shaft 15, which arm is connected to the arm 13 by a tension spring 26 acting to drag the arm 14 along with the arm 13. A roller 25 on the arm 14 engages a surface 29 on the lever 2 while the arm 13 is being rotated to close the switch, but when the operating force is removed, the arm 13 rotates the arm 14 reversely by means of stops 27, 28 and moves the roller 25 to enter a slot 32, thus allowing the spring 5 rapidly to move the lever 2 about pivot 6 and close the switch. When the holding magnets 9 are sufficiently de-energized, the parts are rapidly rotated about the pivot 10 by the springs 5 into open position. The switch may be controlled by a series overload relay the contacts of which are in the circuit of the holding magnet. The contacts may be of the type described in Specification 279,960.

Classes 20(iv), 87(i) and 137 [Also in Group XIII] A sub-ceiling for a room is formed from heat-conducting plates 2, preferably of aluminium, opposite edges 3 of each plate being bent to grip closely tubes 1 heated by hot-water or steam, a layer 4 of heatinsulating material being placed within each plate. The sub-ceiling. may also be used for cooling purposes. Ventilation air may pass through openings 7 in the layers 4 and plates 2 to the space below. The tubes 1 may be suspended from the ceiling proper by brackets, the plates being thrust upwards until the flanges grip the tubes. Alternatively the tubes and plates may be first attached to each other to form units ready for suspension. Specifications 690,279, 690.320 and 690,321 are referred to. The Specification as open to inspection under Sect. 91, comprises also a sub-ceiling constructed from a number of plain and perforated rectangular plates 27, 27<SP>1</SP>, each of which may have recesses on its outer surface for acoustic purposes. The plates 27 are of thin sheet metal and the plates 27' of thin fibrous material or metal. Fresh air is admitted below the ceiling proper through a duct 30 and auxiliary ducts 32. Air flowing through the duct 30 flows through a pre-heating pipe battery 31 and thence over the radiating surface, giving up heat to the radiating surface and to the air admitted through ducts 32. The rocm below is heated partly by radiation frcm plates 27 and partly by the distribution of warm air through the perforated plates 27<SP>1</SP>. Used air escapes through an outlet 33. A thermostat 34 acting on a valve 35 controls the temperature of the battery 31. Alternatively hot air may be introduced into the duct 30, the battery 31 being dispensed with and temperature control being effected by a thermostat 36 controlling a damper 37. To increase heat absorption, ribs 38 may be provided on the plates 27. Girders are used to suspend the plates from the ceiling. Instead of arranging the heating means as a false ceiling it may be constructed as a frieze. This frieze may admit ventilation air and be electrically heated by embedded coils. This subjectmatter does not appear, in the Specification as accepted.

Abstract: 1389372 Gas separation CONSOLIDATION COAL CO 24 Jan 1973 [2 Feb 1972] 3681/73 Heading C1A Sulphur dioxide is removed from a gas stream by a circulating aqueous absorbent containing a sulphite forming compound in approximately the amount required to convert the SO 2  into sulphite and also maintaining therein an amount of thiosulphate in excess of 50% by wt. of the total sulphur compounds in the spent absorbent leaving the scrubber, said thiosulphate having the same cation as the said sulphite forming compound, converting the sulphites in the spent absorbent into thiosulphates while separately converting a portion of the thiosulphate withdrawn from the main circulating stream into sulphite for re-use in the absorption step. Alkali metal carbonates are the preferred sulphite forming compounds and in particular potassium carbonate. When alkaline-earth metal carbonates or hydroxides are used as the sulphite forming compound, they may be formed into slurries rather than as true solutions. Preferably the concentration of sulphite and bisulphite in the circulating absorbent is below 5% by weight. The conversion of sulphite into thiosulphate may be effected by reaction with a reducing agent such as sulphur, hydrogen sulphide, formic acid or a metal hydrosulphide, at a pH between 6 and 7À8.
